To the world she was an icon, but to them she was a friend.

Whitney Houston‘s sudden death last night has left many stunned, most especially R&B stars Brandy and Monica.

The pair, who were being coached by the late singer for their planned performance at Clive Davis’ Pre-Grammy Gala, instead sat in clear disbelief at the solemn event.

Over the years, Houston took on a mentor role for both ladies. Indeed, she maintained a close bond with Brandy, while helping Monica through the suicide of her boyfriend and in other trying times. The singers will no doubt be leaning on each other during this trying time.
